摘要： A magnetic display unit in which a magnetic panel (1) encloses a colored liquid in which magnetic particles are dispersed. A recording head (31) moves over the panel (1) and has a plurality of electromagnets arranged with at least three electromagnets on each of parallel lines inclined to the direction of movement of the recording heads (31) with all the electromagnets being arranged on equal pitch perpendicular to this movement direction. The electromagnets are selectively actuated as the recording head (31) moves to write a dot pattern.

摘要： A ball-point pen for water-soluble ink having a barrel (2) with a vent hole (10), a cylindrical ink reservoir (6) covered except at its exposed front and rear ends (6a, 6b), and an ink feed core (8) for supplying ink from the reservoirto a ball (B) at the pen writing tip is provided with a hollow inner cover member (9) comprising a cylindrical holding part (a)for covering and holding a relatively long front portion of the reservoir (6) and a cylindrical shielding part (9b) for partitioning the front exposed part (6a) of the reservoir and the feed core (8) from the vent hole (10), the inner cover member (9) being secured within the barrel (2) by press-fitting the front end of the shielding part (9b) into a bore (2c) of the front end part (2a) of the barrel.

摘要： A pickup device for picking up vibration transmitted through bones or solid bodies in which a piezoelectric element (6) is disposed like a cantilever within a liquid-tight.case (5) filled with a viscous liquid (8) in such a way that the free end of the piezo-electric element can vibrate with respect to the liquid-tight case. The viscosity of the viscous liquid (8) ranges from 30 to 10000 cs so that the sharpness of resonance of the piezoelectric element (6) can be suitably suppressed.

摘要： A pickup device for picking up sound generated by the vocal chords and transmitted through bones from the nasal bone. A microphone (11) is mounted on or embedded into an eyeglass-like assembly (13, 15). When the microphone is mounted as a nosepiece, it is made into direct contact with the nose so that it directly picks up vibration transmitted through the nasal bone. When the microphone is mounted on the eyeglass-like frame or embedded therein, it picks up vibration transmitted through the nosepieces and eyeglass-like frame. A cord (12) whose end is electrically connected to the microphone is held by holding member extended from the eyeglass-like assembly (13, 15) so that the transmission of mechanical vibration to the microphone is prevented.
